Raws li cov ntaub ntawv luam tawm, yas zaj duab xis rau cov hnab ntim khoom noj muaj keeb kwm luv luv. Nws muaj qhov zoo ntawm lub teeb, pob tshab, noo noo tsis kam, oxygen tsis kam, airtightness, toughness thiab folding kuj, du nto, thiab kev tiv thaiv ntawm cov khoom, thiab nws muaj peev xwm rov tsim dua cov duab ntawm cov khoom. thiab xim. Nrog rau kev txhim kho ntawm kev lag luam petrochemical, muaj ntau thiab ntau ntau yam ntawm cov yeeb yaj kiab yas. Feem ntau siv cov yas zaj duab xis yog polyethylene (PE), polyester aluminized zaj duab xis (VMPET), polyester zaj duab xis (PET), polypropylene (PP), nylon, thiab lwm yam.
Cov khoom ntawm ntau cov yeeb yaj kiab yas sib txawv, qhov nyuaj ntawm kev luam ntawv kuj txawv, thiab kev siv cov khoom ntim kuj txawv.
Polyethylene zaj duab xis yog xim tsis muaj xim, tsis muaj ntxhiab, tsis muaj ntxhiab, tsis muaj tshuaj lom cov khoom siv thermal rwb thaiv tsev, uas yog siv dav hauv kev tsim lub hnab. Nws yog cov khoom siv inert, yog li nws nyuaj rau luam tawm thiab yuav tsum tau ua tiav kom luam tau zoo dua.
Aluminized zaj duab xis muaj ob qho tib si cov yam ntxwv ntawm cov yas zaj duab xis thiab cov yam ntxwv ntawm cov hlau. Qhov saum npoo ntawm zaj duab xis yog coated nrog txhuas los tiv thaiv lub teeb thiab UV hluav taws xob, uas tsis tsuas yog ncua lub txee lub neej ntawm cov ntsiab lus, tab sis kuj ua rau kom qhov ci ntawm zaj duab xis. Nws hloov cov ntawv txhuas txhuas rau qee qhov, thiab muaj qhov zoo ntawm tus nqi qis, zoo li zoo thiab zoo barrier zog. Aluminized films yog siv dav hauv kev ntim khoom. Nws yog tsuas yog siv nyob rau hauv lub ntim ntawm qhuav thiab puffed zaub mov xws li biscuits, thiab txheej ntim ntawm ib co tshuaj thiab tshuaj pleev ib ce.
Polyester zaj duab xis yog xim tsis muaj xim thiab pob tshab, noo noo-pov thawj, huab cua nruj, mos, siab zog, tiv taus acid, alkali, roj thiab hnyav, thiab tsis ntshai ntawm qhov kub thiab txias. Tom qab EDM kev kho mob, nws muaj qhov zoo nrawm nrawm rau number case. Rau kev ntim khoom thiab cov khoom sib xyaw.
Polypropylene zaj duab xis muaj gloss thiab pob tshab, kub tsis kam, acid thiab alkali tsis kam, hnyav tsis kam, abrasion tsis kam, kua muag tsis kam thiab zoo roj permeability. Nws tsis tuaj yeem raug cua sov kaw hauv qab 160 ° C.
Nylon zaj duab xis muaj zog dua polyethylene zaj duab xis, tsis muaj ntxhiab, tsis muaj tshuaj lom, thiab impervious rau cov kab mob, roj, esters, boiling dej thiab feem ntau cov kuab tshuaj. Nws feem ntau yog siv rau kev thauj khoom-cov kabmob, kev ntim khoom tiv thaiv thiab kev ntim khoom retort (khoom noj khoom haus reheating) thiab tso cai rau luam tawm yam tsis muaj kev kho deg.
Kev luam ntawv rau cov yeeb yaj kiab yas suav nrog flexographic luam ntawv, gravure luam ntawv thiab tshuaj ntsuam luam ntawv. Printing inks yuav tsum muaj viscosity siab thiab muaj zog adhesion, yog li cov number case molecules adhere nruj nreem rau cov yas qhuav thiab yooj yim sib cais ntawm cov pa hauv huab cua kom qhuav. Feem ntau, tus number case rau yas zaj duab xis rau gravure luam ntawv yog tsim los ntawm cov khoom siv hluavtaws xws li thawj amine thiab cov kuab tshuaj organic uas muaj cawv thiab xim ua cov khoom tseem ceeb, thiab cov kuab tshuaj qhuav tsis haum yog tsim los ntawm cov pulverization txaus thiab dispersion los tsim cov kua dej colloidal. zoo fluidity. Nws muaj cov yam ntxwv ntawm kev luam ntawv zoo, muaj zog adhesion, ci xim thiab ziab sai. Haum rau kev luam ntawv nrog lub log concave.
Vam tias tsab xov xwm no tuaj yeem pab koj thiab qhia rau koj paub ntxiv txog kev ntim khoom.
